 a) pick a layer

 b) pick a grid that overlaps the above layer

 c) do a "clip" operation with ftools using the grid as "clip layer"

 d) do a "intersect" operation with ftools using the grid as "clip layer"

 e) compare the results, seems to me identical


 Should the "Clip Tool "use just the borders of the "clip layer"?.

 Here you can download the shapesfiles (epsg 20790) I used/resulted in my
 test (qgis 1.2 rev. 11023, Ubuntu 9.04). "Inso" is the base layer, the
 rest are pretty self-explanatory.
